Sigma 2200i - Integrated Amplifier
Introduction
The Sigma 2200i is a powerful stereo integrated amplifier with features like USB and Network streaming, HDMI 2.0 switching and bass management to accommodate the evolving needs of a modern hi-fi system. It leverages the technical and performance advantages of our Sigma series separates to punch seriously above its weight class. As an integrated amplifier, the 2200i combines preamp and power amp functions in a single chassis. What’s special is its direct digital connection between the preamp section and the amplifier, which eliminates losses by removing digital-to-analog and analog-to-digital conversions from the signal path.
The preamp section of the 2200i features connectivity and circuit blocks found in the Delta series CP-800 and Sigma SSP. Inputs include fully balanced (XLR) and single-ended (RCA) analog with optional MM/MC phono, digital coax, optical, USB host and device, Ethernet for streaming and IP control and HDMI switching. Techniques like asynchronous synchronization and master clock mode allow us to manage the digital clocks for low jitter and high signal integrity. Analog sources are converted at 24/96 to preserve their original bandwidth and dynamic range.
Digital Signal Processing is available to all sources; you can use it for bass management with a subwoofer to fill dips in the frequency response in your room while a nine-band parametric EQ can simultaneously eliminate the frequency response peaks; a customizable tone control can tame or add life to your less-than-perfect recordings. It all adds up to better sound from every recording in any room.
Unlike outboard DACs and preamp/processors that must output analog signals for volume control and amplification, the 2200i leverages the true digital architecture of our proprietary Classé switching amplifier design, connecting the output of the preamp DSP directly to the DSP input of the amplifier. There aren’t any DACs or ADCs nor is there any unnecessary analog circuitry between. The signal path is as short and direct as possible; signals remain digital all the way to the amplifier output filters.
From the DSP input to the speaker terminals the amplifier portion of the 2200i is the same as an AMP2 or CA-D200. The input signal comes direct from the preamp DSP, remain- ing in the digital domain throughout. Managing the switching technology to achieve <3 nanoseconds of dead-band time, the 2200i boasts the same low distortion broad-band perfor- mance as our separate amplifiers.
Power is supplied by Classé’s proprietary switch mode power supply with power factor correction. With over 1,000W available, the 2200i coasts through passages that would bring lesser amplifiers to their knees. In addition to supplying clean, rock-steady voltage to the circuitry, this supply pulls power cleanly and efficiently from the wall. And even if you don’t worry about power consumption, you will benefit from the performance and reliability achieved from the comparatively cool-running circuitry contained in the 2200i’s modestly sized chassis.
A front panel touchscreen and both Android and Apple apps provide sophisticated yet intuitive control. DLNA and AirPlay streaming are supported over the Network connection and AV switching with HDMI 2.0 and HDCP 2.2 allows convenient support of set top boxes, games and disc players. Whatever you want to listen to, you can be sure that the 2200i will stand ready to deploy its arsenal of resources, remain faithful to the music and reliably deliver many years of listening pleasure.

How to check the current Firmware of your Sigma 2200i
- Press the MENU button on the left of the touchscreen
- Press STATUS
How to update Sigma 2200i Firmware
- download the latest Firmware package
- unzip the downloaded file on your local computer
- copy the unzipped file onto a new USB key. This key must be empty. The file must be located at the "root" level
- power off your Sigma 2200i using the Power switch on the rear of the unit
- insert the USB stick in the front USB port
- Power on the Sigma 2200i using the power switch in the rear of the unit
- the Firmware update will start automatically and will take xx minutes
- At the end of the Firmware update the unit will ask you calibrate the touchscreen by tipping multiple calibration targets with a tipped object (lead pencil, fingernail, stylus)
What to do when your Firmware Update fails
- simply power down the unit and remove the USB key, the unit should revert back to its previous Firmware Version when your power on again
- insert the USB key into your local computer and open the USB key (file explorer)
- you will notice that 2 LOG files have been written to the USB key. Copy these log file to your local computer. You can send them to Classé Tech Support for further evaluation
- In most cases the software update fails because of an issue with the USB key (previous vendor formatting, file allocation issues). We recommend to buy a clean new USB key and repeat teh Firmware download and update procedure.
Initial Installation
For the initial installation we refer you to pages 9, 10 and 11 of the Owner's Manual.
Extra considerations, based on Customer Service reports:
1. When first powering up the unit, check if the Firmware is Up-to-Date.
Press the Menu button the left of the Touchscreen, then press the STATUS button to check the current FW Version installed. On this Web Page, click on the "Latest Firmware" Tab to see if your unit has the latest FW. If not download the firmware and follow the instructions.
2. Please do send in your Warranty Registration!
Sending in your Warranty Registration via our public website is the best way to ensure that we can reach you for product-related updates.
3. Start by programming your Speaker Configurations, then the Inputs.
Pages 22 to 24 of the Owner's Manual will give you the correct sequence of connecting all equipment.
Many customers, however, stop there and do not take FULL advantage of the unit's powerful sound processing capabilities. By accurately programming your Speaker Configuration(s) your SSP will "know" how to correctly decode and process the incoming signal. In fact, you can create multiple Speaker Configurations and use them according to your Input sources: 5.1.2, 5.1 and Full Range Stereo are amongst the most important configurations. See the Section below.
Once you have programmed your Speaker Configuration(s) you can set up your Inputs which will then allow you to "link" the Speaker Configurations to the Inputs and choose the default Processing Modes you would like to use.
Both the default Configuration as well as default Mode you programmed for a given Input can be overridden in Real Time, if you wish to do so.

Connection to Router
The Sigma SSP has an Ethernet port, capable of receiving incoming High Resolution Audio as well as communicating RS232 Automation Data. Please follow the directives below for optimal use:
- Use good quality CAT5 or CAT6 Ethernet cable;
- Preferably, connect the Sigma SSP MkII directly to your Network Router;
- Make sure the Router Ports mentioned below are open and accessible to the SSP MkII*);
*) Routers provided by Cable Companies or Internet Service Providers will auto-update from time to time, most often whilst you are asleep. If the Sigma SSP starts acting up, then the first thing to do is to see if the Router hasn't simply closed ports during the Auto-Update. The second measure is to reboot (power on/ power off) both the router as well as the Sigma SSP.
Required Router Ports
NOTE: CLASSÉ provided earlier information to "open" certain Router Ports. This information has proven to be incorrect.
Instead, the CLASSÉ App and Router Problem that some customers experience can be explained by a lack of "UDP Multicast" support on certain routers.
"UDP Multicast" is the protocol that the CLASSÉ App uses to communicate its data. We have noticed that certain Internet providers and Router manufacturers either:
- do not "switch on" this protocol by default (it must be activated)
- have stopped supporting it over the last decade.
Customers who experience CLASSÉ App functionality problems must check their routers for Multicast UDP functionality and support. If possible, it must be activated. If Multicast UDP is not supported, the customer should check if another Router can be obtained, or see if a separate wireless router can be installed, one that does support Multicast UDP.
As far as the "Open Ports" is concerned: the list of Ports below is indeed correct. However, customers should NOT open these ports to the World Wide Web (Internet), but make sure these ports are accessible on the internal network (only). Opening these ports to the outside world can pose an elevated security risk.
------
Make sure that the following ports are open on the Router. Without these ports, the unit will not perform its tasks.
Apple AirPlay/Bonjour (Music playback)
- Port 554 TCP/UDP [Real Time Streaming Protocol]
- Port 3689 TCP [Digital Audio Access Protocol]
- Port 5353 UDP [Multicast DNS]
DLNA/UPnP (Music playback)
- Port 1900 UDP
- Port 5000 TCP
Classé App
- Port 35295 UDP
- Port 35296 UDP [Multicast]
TCP Control (RS232 Automation over IP, for Home Automation Systems like Crestron, SAVANT or Control 4)
- Port 50001 TCP
Naming your unit
See Page 44 of the Owner's Manual.
We strongly suggest you give your unit a "Name" that will allow you to find it easily on your Home Network. In order to do this, you will need to read out the assigned IP-Address on the touchscreen, the type this IP address into a Web Browser on a computer (laptop, desktop) connected to the same network. A Sigma SSP Web Page will appear, allowing you to change the name of the unit.
Static IP Address or assigned IP Address?
1. We suggest Owners who use the unit in a stand-alone setting, primarily for Network Audio Playback, to use the default setting (DHCP-assigned IP Address): The unit will get an IP Address assigned by the Home Router
2. For those Owners who use the Sigma SSP through Home Automation (e.g. Crestron, Control4, Savant), a fixed IP Address may be necessary. See the instructions in the Owner's Manual. Once you have assigned a fixed IP Address, you will need to make sure that your Router respects this address. Depending on your Router, you may need to:
- make sure that the fixed IP Address falls outside of the range of "Reserved IP Addresses" that DHCP will use;
- make sure that the SSP's MAC Address is registered in the Router. Since a SSP will not display its MAC Address on touchscreen, we suggest that you use an App like "Fing" to look up the SSP's MAC Address.
Home Automation
The Sigma 2200i can be controlled in a number of ways other than using the Front LED Button, the Touch Screen and the Classé App. the Rear Panel offers an IR-trigger input and output port and R232-Automation over IP via the Ethernet Port.

Procedure:
- On the unit, press the MENU button located at the left of the touchscreen
- Using the small black Classé Remote Control, press -- in sequence ---the buttons F1, F2, F3
- You will now see the menu called "Other Options" (which we also call "Tech Menu")
- Press the button "Restore Defaults"
- That's it. The unit will reset itself and go into Standby
Voltage
- All Sigma Series Products can operate on AC Voltages between 110V - 240V.
- Make sure to change the AC Fuse (rear) to match the AC Voltage of your country.
When you change the fuse to accomodate a different AC Voltage, please contact Classé to obtain a new sticker for the back of your unit that indicates the new Operating Voltage. Without this, another user/customer might make a mistake in applying the correct AC Voltage and the Fuse may blow unexpectedly as a result
Fuse
- Sigma Series components have one AC fuse accessible via the rear panel;
- Make sure that the AC Fuse corresponds to the AC Voltage offered;
